Special Weather Statement, NWS Melbourne, FL

Area Forecast Discussion
National Weather Service Melbourne FL
1105 AM EDT THU AUG 4 2016

.DISCUSSION...Radar/satellite imagery reveals numerous remnant
convective boundaries from earlier convection over/approaching
CWA...along with rapid cumulus development during past hour. 12Z
soundings from XMR/TBW confirm very moist atmosphere throughout
the column...with precipitable water above 2 inches and low LCL's...in
agreement with earlier model progs. Expect significant upward
trend of convective coverage late morning through mid afternoon
with slow motion toward the N/NE. Pattern suggests greatest precip
coverage in some time for CWA...including coastal
counties/beaches. With areal average QPF not likely to be
high...some areas should receive short-duration, beneficial rain
totals today.

With deep moisture and weak winds throughout the vertical
profile, and relatively warm mid level temperatures...threat for
isolated severe storms expected to remain very low.

&&

.AVIATION...Increasing chance for MVFR/temporary IFR in TSRA all
TAF sites through the afternoon...with greatest chance across
inland sites 19-22Z. Several periods of TSRA likely for many
terminals through 24Z.

&&

.MARINE...S/SW flow near 10 knots will become SE 10-15 kt
nearshore this afternoon. Flow will be temporarily and locally
disrupted by offshore-moving, scattered showers/storms.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
ABUNDANT MOISTURE COMBINED WITH LIGHT OFFSHORE FLOW WILL ENHANCE
THE COVERAGE OF AFTERNOON SHOWER AND THUNDERSTORMS STORMS OVER
EAST CENTRAL FLORIDA THIS AFTERNOON. LIGHTNING STORMS ARE EXPECTED
TO INITIALIZE ALONG THE COAST SOUTH OF CAPE CANAVERAL BEFORE
SPREADING SLOWLY WEST AND NORTH THROUGH THE DAY. THE HIGHEST
COVERAGE IS EXPECTED OVER INLAND AREAS FROM OSCEOLA COUNTY
NORTHWARD TO VOLUSIA COUNTY WHERE THE HIGHEST MOISTURE AND
GREATEST BOUNDARY INTERACTIONS ARE EXPECTED TO OCCUR LATER THIS
AFTERNOON. GIVEN THE INCREASED OFFSHORE STEERING FLOW...A FEW
STORMS ARE EXPECTED TO PUSH BACK TOWARD THE COAST LATER TODAY.

TODAYS STORMS WILL BE CAPABLE OF PRODUCING 2 TO 3 INCH DOWNPOURS
IN A SHORT 60 TO 90 MINUTE PERIOD, OCCASIONAL TO FREQUENT CLOUD-
TO-GROUND LIGHTNING, AND WIND GUSTS UP TO 40 MPH.

.RIP CURRENT IMPACT...
A LINGERING EASTERLY SWELL WILL LEAD TO A MODERATE RISK FOR RIP
CURRENTS...MAINLY ALONG THE BEACHES OF VOLUSIA AND BREVARD
COUNTIES. IF HEADED TO THE COAST, CHECK WITH LOCAL BEACH PATROL
BEFORE ENTERING THE WATER AND ONLY SWIM WITHIN SIGHT OF A
LIFEGUARD.

.MARINE THUNDERSTORM GUST IMPACT...
STEERING FLOW OUT OF THE SOUTHWEST WILL INCREASE THE THREAT FOR
OFFSHORE MOVING THUNDERSTORMS TODAY. INITIAL DEVELOPMENT OF
LIGHTNING STORMS CAPABLE OF PRODUCING GUSTY WINDS IS EXPECTED
ALONG THE SPACE AND TREASURE COASTS AS THE EAST COAST SEA BREEZE
DEVELOPS LATE THIS MORNING AND EARLY THIS AFTERNOON. STORMS
CAPABLE OF PRODUCING WIND GUSTS IN EXCESS OF 34 KNOTS ARE POSSIBLE
OVER INLAND LAKES AND RIVERS THIS AFTERNOON AND EVENING...SOME OF
WHICH COULD PUSH BACK TOWARD THE COAST.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
ABUNDANT MOISTURE WILL LEAD TO AN INCREASE IN COVERAGE OF SHOWERS
AND LIGHTNING STORMS THROUGH THE WEEKEND. OFFSHORE STEERING FLOW
WILL ALLOW SOME OF THE STORMS TO PUSH OFF THE MAINLAND AND OVER
THE INTRACOASTAL AND NEARSHORE WATERS OF EAST CENTRAL FLORIDA.
FREQUENT LIGHTNING...HEAVY DOWNPOURS AND GUSTY WINDS WILL BE THE
MAIN HAZARDS IN ANY STRONGER STORMS WHICH DEVELOP.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT ANTICIPATED TODAY.
